| Popis: | This paper presents methodology and results of a research project on software optimization of combustion process efficiency in coal-fired power plant. The general goal of this project was to increase boiler efficiency by proper control of the combustion process using optimization software, integrated with Distributed Control System and in-furnace temperature profile measurement system. The research goal relays on new approach in combustion modelling based on in-furnace temperature distribution and utilization of this model in on-line boiler control. it is assumed that this approach allows for more precise control of the combustion process, what finally has a positive influence on boiler performance – the efficiency in specific. The solution has been designed, installed and tested on existing, utility plant – 225 MW (650 t/h of nominal steam generation). Final analysis has shown positive results – the boiler efficiency increased over 0.25%. |
